The fraud called REDBUS. I booked my ticket on redbus on V2K travels. Bangalore to Chennai. I wanted to advance it by a day. I had paid 1400. It mentioned no fee for date change. Finally, I was forced to pay another 450!!! I had to travel and I paid. The next morning fares were quoting 800/900. The travels were very polite when I spoke on this but REDBUS never bothered to address the issue. They charge exorbitantly. Never use this fraud. Till now no feedback.
